SIGLENT Prepare Information Before initiating performance verification or any adjustments, it is recommended to follow these procedures. The following topics are discussed in this chapter. How to perform functional checks How to operate four standard interface tests How to use the self-calibration routine How to recall factory Default settings For more detailed information about analyzers operation, please refer to the SVA1000X User Manual.
SIGLENT Note: To avoid electric shock, make sure that the instrument is correctly grounded to the earth before connecting AC power. Press the power-on button located at the lower left corner of the front panel and some keys will illuminate for about 6 seconds. Then, the boot screen will appear on the display. The front panel is shown in the figure below.
SIGLENT Interface Test The SVA1000X series spectrum analyzer is designed with four standard interfaces: USB Host, USB Device, LAN and a 3.5 mm mono jack for an earphone. Being connected to other instruments via these interfaces enables the analyzer to achieve even more enhanced capabilities. In order to ensure the analyzer is operating properly, it is recommended to first test the interfaces. USB Host Test To test if the USB Host interface is working normally. Tools: ● USB memory device (U disk) Steps： 1.
SIGLENT USB Device Test To test if the USB Device interface works normally. Tools： ● A computer with USB interface that is compatible with running National Instruments NI-MAX software ● A standard USB cable (Type A-B) ● NI-MAX software Steps： 1. Download and install National Instruments NI MAX software by following the installation instructions provided by National Instruments. 2. Connect the analyzer USB Device port and the computer using an USB cable. 3. Run NI MAX software.
SIGLENT LAN Port Test Use to test the LAN interface functionality. Tools： ● A computer with functional LAN interface and DHCP activated. ● A standard LAN cable Steps： 1. Connect the spectrum analyzer and the computer using a LAN cable via LAN interface. 2. Press System -> Interface ->LAN, Set the IP Config to DHCP, as the figure below shows. The analyzer will set the IP Address and Subnet Mask and Gateway automatically in this network. Write down the displayed IP address. It will be used in later steps.
